_Pilots for 9/11 Truth, an organization dedicated to uncovering what happened on 9/11, previously confirmed that United 175 received a message at least twenty minutes after it allegedly crashed into the World Trade Center. It has now proven that United 93 was flying over 500 miles away from its alleged crash site AT THE TIME IT SUPPOSEDLY CRASHED! The book Planes without Passengers: the Faked Hijackings of 9/11 advances the theory that neither flight 175 nor 93 crashed that day but were instead flying long after the times of their alleged crashes.
